🚀 go-pugleaf

I would like to iterate thru some selected rows of a table to set their filcolors like this:

 
var mySel = app.selection[0].rows 
var myCols = ["Green", "Green", "Blue", "Red"]; 
var myCounter = 0

for (oneRow = 0; oneRow < mySel.length; oneRow++) 
{ 
	mySel[oneRow].fillColor = app.documents[0].swatches.item(myCols[myCounter]); 
	if (myCounter < myCols.length-1) 
	{ 
		myCounter++ 
	} 
	else 
	{ 
		myCounter = 0 
	} 
} 




But this script does not apply the fillColor from the first row of selected rows upwards to the last row of the selected rows, but from the first row of the parent table to the count of selected rows.

How can I adress the first row of the selected rows?

Thanks
Martin
